What Should The Red Sox Do On/Before The Trade Deadline?

Who should the Red Sox get? Pitching, hitting defense? Or maybe they could even be sellers, hit the jump to see my opinion. Tradeable Pieces:

Mike Lowell 3B/1B- The Indians, Tigers, and the Giants had interest in him a while ago. It went down for a while, and then it ( presumably) spiked up after his 3 HR performance.

Jacoby Ellsbury OF- The Red Sox are very upset with him, they really want him on the field, and off of his butt, in Arizona.

Adrian Beltre 3B- As much as I hate to say it, he is a tradeable piece, hopefully he isn't. I believe he loves it here, and he should get all the money he deserves.

Casey Kelley P- Our number 1 prospect according to SoxProspects.com and a huge talent. He is having a down year in AA Portland, but is getting a lot of strikeouts and everything should go uphill from here

Jose Iglesias IF- Young, Cuban prospect in AA, and is having a plus year. No power, but good contact.

Ramon Ramirez/Manny Delcarmen MR: Although we are looking for pitching, these people are both tradeable.

Who the Red Sox want:

Scott Downs MR: Good lefty pitcher that has proven himself in the AL East(That is VERY important to all interested teams, especially the Sox and the Yankees.)

Jayson Werth OF- Good power, good contact, good fielding, will be our everyday left fielder.

Joakim Soria MR: Very good reliever, exactly what the need.

Josh WIllingham: OF- Good defensive, plus contact and power.

That's basically it, the Red Sox need to get one of those four people, at least. Scott Downs has the highest asking price out of all of them, so they are all real possibilities, and I do expect them to be buyers, not sellers, at the deadline.
